? 2022 Phytochemical Society of EuropeUliginoside H (1) is a new resveratrol trimer diglucoside derivative with fused heptacycles. It was discovered from the acetone extract of the stem bark of Shorea uliginosa (Dipterocarpaceae). Spectroscopic analysis, such as NMR experiments, was used to elucidate the structure, and the absolute configuration was determined using circular dichroism data. Notably, 1 has a fused ring system composed of a dihydrobenzofuran ring, a hexahydrocyclopenta[c]chromene ring, and a cyclohex-2-enone ring, each with eight asymmetric carbons. Thus, a plausible biosynthetic pathway for 1 was proposed.
